Embodiment
Below in conjunction with drawings and Examples the present invention is described in detail.
The theory diagram of infrared photoelectric passenger flow device of the present invention is seen Fig. 1.Mainly form by infrared electro transmitter array, photoreceptor array, control/judging unit, demonstration transmission unit and power down protection unit.
The infrared electro transmitter array is made of at least two row's infrared electro transmitters, and photoreceptor array is made of two row's photelectric receivers at least, has relation one to one between each transmitter of transmitter array and receiver array and each receiver.Row's number and every row's transmitter or receiver number determine that according to actual conditions this device adopts two rows, every row's 16 (8 couples) transmitter and receiver array.Among Fig. 1, transmitter 1a ... Na respectively with receiver 1a ... Na is corresponding one by one, transmitter 1b ... Nb respectively with receiver 1b ... Nb is corresponding one by one.During use, transmitter array and receiver array are installed in the both sides of door respectively, and close the position of corresponding emitter array and receiver array is correlation.Transmitter array and receiver array are installed alignment in the horizontal direction, on the height apart from about 1 meter on ground.
The infrared electro transmitter is made up of infrarede emitting diode and trigger circuit; The infrared electro receiver is made up of infrared integrated receiving circuit.The infrared ray frequency of operation that transmitter is launched is by control/judging unit output signal decision, so can be according to the different choice of working environment different infrared ray frequency of operation.The operating distance of transmitter array and receiver array can be regulated as required.
Control/judging unit mainly is made of microprocessor and peripheral circuit thereof.The infrared transmitter array transmits under the control of control module.Judging unit is gathered the signal that photoreceptor array receives and is also handled, and distinguish people and object according to the ergonomics algorithm, thereby whether the someone passes through in judgement, the direction that the people passes through (be into or go out); When many people passed through simultaneously, judgement was by people's number.Control/judging unit is realized by software that mainly the programming of control/determining program is in microprocessor.
The demonstration transmission unit is made up of display device and RS485 communication serial port (or RS232 communication serial port).Display device is to be used for showing the data such as the volume of the flow of passengers that come out.The RS485 communication serial port can send statistics to other device.
The power down protection unit mainly is made up of battery and holding circuit.When the power supply power supply instability or when going wrong, the power down protection unit can automatically switch to battery powered mode, prevents the loss of data that comes out.
Photoelectric sensor in the embodiment of the invention adopts the correlation mode, in fact, also can reflect mode.
Fig. 2 is control of infrared photoelectric passenger flow device and judging unit flow chart.In the infrared photoelectric passenger flow device course of work, transmitter array sends signal always.The working method on all each roads is identical, and receiver array is in accepting state.Direction judgement among Fig. 2 is the emphasis of native system by judgement with the identifier.
The judgement of A, direction is that each arranges the order that the photoelectricity receiving array receives infrared light, judges the human body direction of passage when passing through system according to the people, in other words, is to judge according to the order that infrared light is blocked.Native system has adopted and has entered and left the two judgements of system orientation, and requires the both direction unanimity, just counting.The two judgements of direction can prevent that the people from stopping at passenger flow system determination place, and rock and the repeatedly counting that causes front and back; In the time of can preventing that also many people from passing through simultaneously, infrared light blocks chaotic in proper order and counting error that cause.
The judgement that B, identifier pass through realizes (Fig. 3) by the manikin algorithm, and the manikin algorithm is made up of three parts: be respectively the head judgement, body judgement, lower limb judgement.
The head judgement is the core of manikin algorithm, because when a plurality of people walk simultaneously, the each several part of health all may be in contact with one another, but people's head is difficult to touch together when walking, so the manikin algorithm that native system adopts is adjudicated from the head part.The head decision algorithm is sought the object similar to head at first from the top down; After finding similar object, carry out the head judgement.Judgment condition is greater than r, and less than the approximate spheroid (r and R value can set up on their own) of R.
The body judgement is the important judgment condition of manikin algorithm.The body judgement mainly contains two parts and forms: be respectively just to descend body judgement and the judgement of crooked body.The great majority body was under head when the people walked, but health is to lean forward or swing back when also having by evidence that seldom some people is walked, so the body judgement divides two parts to carry out.The body decision algorithm is that the object from tight connector subordinate portion begins, and the condition of body judgement is closely to be connected with head, and shape approximation rectangular parallelepiped (just descend body to adjudicate) or bending (crooked body judgement) occupy certain volumetric spaces.
The lower limb judgement is that the manikin algorithm replenishes judgment condition.Because the height of the person, fat or thin, factor differences such as limbs sound, the characteristics of walking are so the judgement of lower limb has produced difficulty.What native system adopted is single lower limb judgement mode, and it is just passable promptly to have detected one leg.The lower limb judgement is that the object below being close to body begins, and to ground above L centimetre (distance of L can set up on their own), and the cutting-out limb should be continuous.
Head judgement and the main judgment condition of body judgement as the manikin algorithm, lower limb are adjudicated condition as a supplement, only just adopt under the very high condition of precision prescribed.
